To all whom it may concern: Be it known that l, RUBIN Bass, a citizen of the United States, residing at New York, county and State of New York, have invented certain new and useful llnlprovements in Binding-Holders, of which the following is a specification.

The general object of the present invention is to provide a neat and efiective holder for binding and to adapt the holder for connection to the binder tool of a sewing machine; and further to adapt the holder to tension the binding to a degree corresponding to that at which the material is tensioned in the operation of sewing the blnding thereunto. And to these ends the invention resides in a reel adapted to be readily,

connected to the roll of binding and provided with adjustable means for frictionally contacting with the roll of binding .and further in providing a casing for the reel and adapting this casin 'for connection to the binder tool and for directing the binding thereinto.

- Uther objects will appear and be better understood from that embodiment of my invention of which the following is a specification-reference being bad to the accompanyin in while Figure l, is a plan view-of the invention inuse.

Fig. 2, is a vertical cross sectional detail taken through the reel and the casing.

l 'g. 3, a detail perspective of one'section of the reel hub. e

hig. 4L, is a view similar to Fig; 3, of another sectionof the reel hub.-

The casing which is indicated generally by a may be formed of any material found suitable for. the purpose as for instance metaL- The reel which is indicated generally by h is referably formed of the same material as to casing The binder tool which is indicated genera-ll by is of well lmown construction. he .reel 5 is disposed in casing a and the head-5, of the said reel is removable sons to facilitate the arrangement of the roll of'binding 6,

thereon. From the 5 roll 6, the binding passes through acontracted throat or pas 'l', into the throat or passage of the binder tool c. --The .throat orpassage 7, is disposed as a radial extension of easing a and is suitably adapted to be connected to the binding tool 0. In the present inthrong drawings forming part hereof, andreel turns. The central opening in the roll of binding 6, receives the outer tubular sec tion'13, of the hub, which section is'so pro portioned as to nicely fit in the central opening of the rolland thus prevent the latter from moving bodily while being unwound. The tubular section 14, of the hub telescopes into section 13, and the closed upper end of the section 141: forms a support for the head. 5 .of the reel 6.

I I I v spring 16, forms a support for the section 14%, pt the hub and is adapted to maintain section it slightly projected beyond section 13, so that the intervening space between head 5 and bottom 12 will correspond approximately to thethiclsness of the roll of binding 6. A screw threaded pin 17, passes alining openings in the bottom 10, bushing ll, bottom 12, end 18 of section 13, to 15 of section 14, and the head 5 of reel 5? A winged nut 19 or its equivalent, is screwed onto the pin 1'7, and when turned in one direction operates 'to telescope secti s 13 and 14 of the hub and thereby move the head -5 nearer to bottom 12 and into closer contact withthe roll 6 of the binding. i

This feature of adjustability on the part of reel 6 is of importance in that it admits of placing a tension-on the roll 6, by the act of moving head 5nearer to bottom 12; in

the operation of binding an edge which ex- 1 tends parallel with or at right angles to the warp of the material there will be little or no tendency on the part of the material to stretch under the pull which is invariably ice exerted by the action'of thefeed bar and the hand of the operator in guiding the material to the sewlng needle'QO and under the Presser foot 21. But in binding an edge which extends obliquely to the warp of the material the same is invariably stretched by the pull exerted by the feed bar and the hand 0 the operator; with the result that the operator is required to stretch the bindin to the same extent as the material in or or to avoid. buckling of the binding.

' edge disposed at right angles or parallel with the warp of the material.

It will now be obvious that, since the present invention admits of automatically stretching the binding by effecting compression of the roll thereof to the required head 5.

extent between the head 5 and bottom 12, there is not required in binding bias edge material any greater degree of caution than in binding an edge extending parallel or at right angles to the warp. One of the sections of the hub has a toot or projection 22 which is received by a recess 23 in the other section. In'the present instance I have shown the tooth forming part on section 14 and the recess arranged in section 13. With this constructionit is obvious that the sections of the hub may be interlocked and the parts of reel 'b made to rotate as a unit when finger pressure exerted in the required direction is applied to This feature of rotatability in the reel will be found desirable in retracting the free end be found extending beyond the binding tool after the device is detached from the machine cl The device of this invention may be attached to any conventional type of for use on sewing machines,

sewing machine by the clamp screw 24, which extends through the slot 25 of rib 26, which is so connected to casing a and binding tool 0 'as to form a brace and give stability to the device.

What is claimed as new is:

1. A reel for holding binding and adapted embodying a casing provided with a tape-feeding outlet, a disk, forming one of the sides of the reel mounted within the casing, a cooperating disk, forming the other side of the reel, positioned in spaced relation thereto, a tubular section extending inwardly from one of said members, a cooperating tubular section extending inwardly from the other of said members in telescopic relation to each other, a spring housed within one of said tubular sections and tending to force the side members apart and means for securing the several elements together and adjusting the tension on the spring. a

2'. A reel for holding binding and adapted for 'use on sewing machines, embodying a portion of the binding which may casing provided with a tape-feeding outlet, a side member of the reel positioned within said casing, a tubular member extending at right angles therefrom formingone of the elements of the hub of the reel, a second side member positioned in spaced relation to the specified side member, a tubular section cotending to force the side members of the reel apart.

3. A reel for holding binding and adapted for use on sewing machines, embodying a casing provided with a tape-feeding outlet, a side member of the reel positioned within said casing, a tubular member extending at right angles therefrom forming one of the elements of the hub of the reel, a second side member positioned in spaced relation to the specified s'ide member, a tubular section cooperating with said second side member and telescopically arranged with reference to the tubular section of the first side mem ber, whereby the distance between the members may be regulated, means for locking the tubular sections together so that, if desired, they may be rotated as a unit, means embodying a bolt and nut for securing said specified elements together, and a tension spring, thetension of which is controlled by the bolt and nut, tending to force the side members of the reel apart.

4. A reel for holding binding and adapted for use on sewing machines, embodying a casing provided with a substantially radially r extending contracted opening through which the tape may be fed, a reel mounted on the casing embodying spaced side members, a tubular section extending inwardly from each of said side members and forming the hub of the reel, said sections being telescopically arranged with relation to each other, a tension spring housed within one of said tubular sections and tending to force the side members of the reel apart and unitary means for securing the side members and tubular sections together and for regulating the tension on the spring.

In testimony whereof I have signed my name to this specification this 16th day of February 1916.
